Itunes update aborts - error "signature could not be verified"

I have attempted several times to download and install the latest iTunes update (11.2). The install keeps aborting with the error message "itunes signature could not be verified." I tried downloading only, and still get a similar error message. Please don't ask me for the error message number - I didn't record it.
I am running iTunes on Windows 8. I've been able to install previous updates since migrating to a Windows 8 machine. Is this a known issue? If so, how do I solve it?

I notice this has happened with previous versions of iTunes as well as previous versions of Windows. I don't see any posts as yet about 11.2. Am attempting to download via the Apple website as suggested in replies to previous instances of this error. I will let you all know the result. I'd really like to know WHY this happens! Is it related to iTunes or Windows? If someone could explain in reasonable layperson's terms, that would be helpful. This is obviously a known issue for quite some time (posts going back to 2010-2011); why hasn't it been addressed? We should be able to download iTunes updates from within iTunes!
Thanks!

PGP signatures could not be verified

I'm still somewhat new on using makepkg. I previously customized the bind pkg for samba by copying the /var/abs/extra/bind directory into my /var/abs/local and adding a couple of build options. Worked like a charm and no issues.
Today bind 9.10.2 was released and I wanted to update my package but I get:

I saw automatic importing of missing keys in this BBS thread. Don't know if it is in the ArchWiki though.
Just found it here: https://wiki.archlinux.org/index.php/Ma … e_checking
It is a personal preference, I don't want to import Arch/AUR keys into my normal personal keyring - but reading the gpg (and makepkg) manpage it looks like if you set GNUPGHOME=/some/path first that should work to set a special keyring just for AUR and a custom config from the wiki.

HELP ME!!!! itunes wont open, error says could not open key......

I attempted to update itunes to the newest upgrade, and the upgrade was unsucceful, and now this error comes up everytime i try to open itunes (it wont open at all). the error says
Could not open key:
HKEYLOCALMACHINE\Software\Classes\.wav\OpenWithList\iTunes.exe.
Verify that you have sufficent access to that key, or contact your support personnel.
This makes no sense since this is on my home PC

hmmm. okay, if you're currently just getting the "itunes has encountered an error ..." let's try the following technique.
preliminaries
download and save a fresh copy of the itunes 6.0.1.3 installer to your hard drive. (eventually we're going to run the install from there rather than online.)
iTunes 6.0.1.3 Installer
switch off any antivirus and antispyware applications prior to any uninstalls, installs or repair installs.
uninstall
use the complete uninstall instructions given in the following document to remove your existing itunes and quicktime:
Troubleshooting iTunes, iPod Software, and QuickTime installation on Windows
... and if you run into problems on the uninstall, try using the Installer Cleanup utility:
Description of the Windows Installer CleanUp Utility
reboot after uninstalling.
reinstall
remember to switch off your antivirus and antispyware.
reinstall itunes using the 6.0.1.3 installer you downloaded previously.
if you get the "itunes has encountered a problem ..." error message again after that install, first check to see if your Quicktime will launch. if you get an error message when you try to launch quicktime, try using the following technique:
iTunes 6 for Windows unexpectedly quits when opened
keep us posted on your progress.

[SOLVED] PGP signature could not be verified!

I am trying to install password safe from the AUR.
I have downloaded and un-tarred the tar.gz file but when I execute makepkg -s I get the following error:
$ makepkg -s
==> Making package: passwordsafe 0.94.1BETA-1 (Mon Dec 29 21:41:00 PST 2014)
==> Checking runtime dependencies...
==> Checking buildtime dependencies...
==> Retrieving sources...

==> Verifying source file signatures with gpg...
pwsafe-0.94.1BETA-src.tgz ... FAILED (unknown public key 919464515CCF8BB3)
Following the instructions on the "Package Signing" wiki, I:
$ sudo pacman -S haveged
$ sudo systemctl start haveged.service
$ sudo pacman-key --init
$ sudo pacman-key --populate archlinux
$ sudo pacman-key --add pwsafe-0.94.1BETA-src.tgz.sig
[sudo] password for xxxxx:
==> Updating trust database...
gpg: next trustdb check due at 2016-01-22
makepkg -s still fails at this point.
The next steps on the wiki call for:
1. verifying the fingerprint with: $ pacman-key -f keyid, and
2. locally signing the imported key with: # pacman-key --lsign-key keyid
How do I determine the "keyid"?
If I use the 'public key' returned in the error message above, I get:
$ pacman-key -f 919464515CCF8BB3
gpg: Note: trustdb not writable
gpg: error reading key: No public key
==> ERROR: The fingerprint of a specified key could not be determined.
And if I use the name of the file I downloaded with the tar, I get:
$ pacman-key -f pwsafe-0.94.1BETA-src.tgz.sig
gpg: Note: trustdb not writable
gpg: error reading key: No public key
==> ERROR: The fingerprint of a specified key could not be determined.
I even tried un-tarring the signature... but that didn't work either.
$ tar xzvf pwsafe-0.94.1BETA-src.tgz.sig
gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now
I also searched through pacman's keyring directly with:
$ gpg --homedir /etc/pacman.d/gnupg --list-keys
but I didn't see the packager's name or email address anywhere.
A nudge in the right direction would be greatly appreciated.
Cheers,

Thank you to everyone who replied!
It has taken me a while to read all the links and try to understand them.
My main problem was that I was mixing up package signing (via pacman) with package signing (via makepkg). The two are related, but separate: they both use gpg, they both use keys that can be downloaded from key servers, they both use keys that can be locally signed, they both use key-rings... but the key-rings they use are different, and process they use to install and validate those keys is also different. (Correct me if I'm wrong.)
From the Wiki
The signature checking implemented in makepkg does not use pacman's keyring.
In my case, I'm installing from the AUR. The error I received:
FAILED (unknown public key 919464515CCF8BB3)
was because makepkg could not find the supplied key in my personal key-ring.
All I needed to do was:
1. Download the key.
2. Add it to my personal key ring.
3. Trust it.
Alternatively, I could build the package by skipping the check.
Download the Key
1. Download from the MIT key server. Enter the keyid as a 16-digit hex number, e.g., 0x919464515ccf8bb3. Right-click on the result and save to the desktop [see Roken's post] above. Or,
2. Try the command line per jasonwryan's post above. (This number does not need to start with 0x.)
I tried both of these methods to verify that they work. They do.
Add the key to my personal keyring
With jasonwryan's method, the key is added as part of the command. With Roken's method an additional command is needed:
gpg --import /path/to/saved/keyfile
If I try makepkg -s at this point I still get an error... but the error is different. It is now:
FAILED (the public key A703C1328EABC7B201753BA3919464515CCF8BB3 is not trusted)
which brings us to the third step.
Trust It
$ gpg --list-keys # to get the correct keyid
$ gpg -edit-key keyid # from the previous command
gpg> trust
At this point, gpg asks the user how much he trusts this key. If you're like stevenhoneyman you might say, "Er... not very much" and opt for building without trust.
Or you can grant a lot of trust in order to create the package and then revoke the trust later (but I'm guessing this will cause problems when the package needs to be updated).
A level of 5 "Ultimate Trust" was required to build this package.
Thanks to everybody who helped me out with this. Definitely a learning experience!

9.2 ITunes Update " Windows Installer Service Could Not Be Accessed" HELP!

I'm running Windows 7 64 bit OS system and I have no problems installing or uninstalling anything on my computer EXCEPT Itunes. I have not been able to install the new update to 9.2 and I need to before I can get the new Iphone software for my new IPhone 4.0 tomorrow.
Please help, this is my work phone and I have gone to every support place possible to fix this.

After much searching I found the following solution...it worked for me. So simple you would think the Tech guy at HP I spent an hour on the phine with would have known it. Good luck!
This is the solution that worked for me:
Go to this registry key:
HKEYLOCALMACHINE\SYSTEM\CurrentControlSet\Services\MSIServer
Look for
WOW64 and it's value.
Is it 0x00000001 (1) ?
This value tells Windows Installer only to deal with 32-bit installers
and to return you an error whenever you try to install something that is
64-bit. To fix it, just set the value to 0. So you will see in your
editor:
WOW64 REG_DWORD 0x00000000 (0)
After changing the value to zero, restart your Windows Installer Service
by using services.msc or reboot.
This simple solution of changing the 1 to a 0 allowed me to finally
install Itunes on Vista 64

Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased. Some glitch occured and you have to restore/erse the iPod. Y will have to restore from an existing backup if y ohave one.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.

For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

For anyone that comes across this. I managed to fix the problem. It had something to do with the date on my computer. Mavericks installer apparently does a date check of some sort and that is where the error is coming from. Open terminal and check the system date. It may be wrong. Another poster in the forums told me how to to check the date and change it. Click here for the link to the explanation. Be careful because the date is in a weird format.

If I have lost my music collection I will be switching platforms ASAP. It is insane that Apple has updates seemingly every day for their products.

I was in your same situation with 14 downloads and 14 attempts.
You have to make sure that your Mac is booting into 64 bit mode. You can make sure of this by going into System Preferences and scrolling down to 'Software' and making sure that you are booding with 64 bit Kexts.
If not, restart while holding the 6 and 4 keys down until you see the spinning gear wheel and try installng again.
BUT, what I also did was to go into Applications, click on the Lion installer, Get Info, and give yourself custom priviliges to Read And Write.
I did this simultaneously, and I don't know what function did it, but it worked for me, with no further downloads of the installer.
Good luck!
